Silafluorene-based polymers for electrochromic and polymer solar cell applications
ERLIK, Ozan; UNLU, Naime A.; HIZALAN, Gonul; HACIOGLU, Serife O.; COMEZ, Seda; Yildiz, Esra D.; Toppare, Levent Kamil; Çırpan, Ali (Wiley, 2015-07-01)
In this study, four novel silafluorene (SiF) and benzotriazole (Btz) bearing conjugated polymers are synthesized. In the context of electrochemical and optical studies, these polymers are promising materials both for electrochromic device (ECD) and polymer solar cell (PSC) applications. All of the polymers are ambipolar (both p- and n-dopable) and multichromic. Electrochemistry experiments indicate that incorporation of selenophene instead of thiophene unit increases the HOMO energy level of the polymers. P...
Silica embedded cobalt(0) nanoclusters: Efficient, stable and cost effective catalyst for hydrogen generation from the hydrolysis of ammonia borane
Metin, Onder; Dinc, Melek; Eren, Zeynep Seda; Özkar, Saim (2011-09-01)
Cobalt(0) nanoclusters embedded in silica (Co@SiO2) were prepared by a facile two-step procedure. In the first step, the hydrogenphosphate anion (HPO42-) stabilized cobalt(0) nanoclusters were in situ generated from the reduction of cobalt(II) chloride during the hydrolysis of sodium borohydride (NaBH4) in the presence of stabilizer. Next, HPO42- anion-stabilized cobalt(0) nanoclusters were embedded in silica formed by in situ hydrolysis and condensation of tetraethylorthosilicate added as ethanol solution....

Ergül, Zeynep; Volkan, Mürvet; Özkan, Necati; Department of Micro and Nanotechnology (2012)
Magnetic nanoparticles find broad applications in biomedical field such as drug delivery, hyperthermia and magnetic resonance imaging (MRI). For these applications magnetic nanoparticles need to be coated with suitable materials which are soluble, biocompatible and nontoxic. Among these materials, silica is the most often used coating material. This thesis is focused on preparation of silica coated iron oxide magnetic nanoparticles. Magnetic iron oxide nanoparticles are synthesized by thermal decomposition ...

We present a microfluidic reactor that utilizes meandering microchannel shape to mix reagents inside droplets in a carrier fluid to synthesize silica and silica coated nanoparticles. Meandering channels decrease mixing time due to reduced diffusion lengths. Moreover; droplet-based flow provides uniform reaction times due to the circulating flow profile inside droplets as opposed to parabolic flow profile in straight channels. Before fabricating our device, we have simulated the mixing performance of droplet...
Selenium doped calcium phosphate biomimetic coating on Ti6Al4V orthopedic implant material for anti-cancer and anti-bacterial purposes
Yılmaz, Bengi; Evis, Zafer; Banerjee, Sreeparna; Department of Biomedical Engineering (2014)
In order to prevent recurrent osteosarcoma in patients undergone surgical resection for implant insertion and infection around implant site, which is a very common complication after surgery, it is very important to functionalize the surface. In this study, to combine the effective antioxidant and potential anti-cancer and anti-bacterial properties of selenium with the high biocompatibility and bioactivity of hydroxyapatite, selenium was added to the structure of hydroxyapatite via biomimetic method and coa...
